i use freeware sensorlock application, search it from xda-developers.com forums. It locks phone when you turn your phone 360decree clockwards and unlocks in opposite direction (uses g-sensor). Wery useful!
We've been trying this pretty hard already - but didn't manage to get it done for all devices. Problem is, that when you lock all keys (there is indeed an API function for that), you cannot access some keys any more at all. But those are the keys that would be required to return to the "unlocked" mode ...
